The London protest on September 13, 2025, known as the "Unite the Kingdom" rally, was primarily about opposition to immigration. It was led by far-right activist Tommy Robinson and drew over 100,000 participants, making it one of the largest right-wing demonstrations in recent UK history. The protesters voiced concerns about illegal immigration, national identity, and freedom of speech, with many displaying symbols such as the Union Jack and chanting slogans calling for migrants to "go home." The rally was marked by clashes with police and about 26 officers were injured, some seriously, during confrontations between protestors and law enforcement. There was also a counter-protest organized by anti-racism groups that attracted around 5,000 people. The event highlighted rising nationalism and tensions around migration in the UK, fueled by misinformation and coordinated far-right activity on social media platforms.
